* tree-ssa-loop-ivcanon.c (tree_estimate_loop_size): Add edge_to_cancel parameter and use it to estimate code optimized out in the final iteration. (loop_edge_to_cancel): New function. (try_unroll_loop_completely): New IRRED_IVALIDATED parameter; handle unrolling loops with bounds given via max_loop_iteratins; handle unrolling non-inner loops when code size shrinks; tidy dump output; when the last iteration loop still stays as loop in the CFG forcongly redirect the latch to __builtin_unreachable. (canonicalize_loop_induction_variables): Add irred_invlaidated parameter; record niter bound derrived; dump max_loop_iterations bounds; call try_unroll_loop_completely even if no niter bound is given. (canonicalize_induction_variables): Handle irred_invalidated. (tree_unroll_loops_completely): Handle non-innermost loops; handle irred_invalidated. * cfgloop.h (unlop): Declare. * cfgloopmanip.c (unloop): Export. * tree.c (build_common_builtin_nodes): Build BULTIN_UNREACHABLE. * gcc.target/i386/l_fma_float_?.c: Update. * gcc.target/i386/l_fma_double_?.c: Update. * gfortran.dg/do_1.f90: XFAIL * gcc.dg/tree-ssa/cunroll-1.c: New testcase. * gcc.dg/tree-ssa/cunroll-2.c: New testcase. * gcc.dg/tree-ssa/cunroll-3.c: New testcase. * gcc.dg/tree-ssa/cunroll-4.c: New testcase. * gcc.dg/tree-ssa/cunroll-5.c: New testcase. * gcc.dg/tree-ssa/ldist-17.c: Block cunroll to make testcase still valid.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
